Application filed September 16, 1898. 1 Serial No. 691,108. (No model.)

To a/ZZ whom it 71mg/ con/cern.'

Beit known that I, ALBERT J. KECK, a citizen of the United States, residing at St. Paul, in the countyof Ramsey and St-ate of Minnesota, have invented, certain new and useful Improvements in Magazine Lead-Pencils, of which the following isa specification.

This invention relates to pencil or crayon holders in which a series of short sections of the pencil are held in a holder and from which they are adapted to be ejected when required for use; and the invention consists in the construction, combination, and arrangement of parts, as hereinafter shown and described.

In the drawings illustrating the construction, Figure l is a sectional elevation showing the interior construction. Fig. 2 is a crosssection on the line o: of Fig. 1. Fig. 3 is a cross-section on the line y y of Fig. 1. Fig. 4 is a perspective View of one of the crayon or pencil holding tubes detached. Fig. 5 is a detached perspective view of the form of the ejector-tube employed in the modiication shown in Fig. 1. Fig. 6 represents a number of the crayon or pencil sections detached. Fig. 7 is a View similar to Fig. 1, illustrating a modiiication in the construction. Fig. 8 is a perspective view of the form of ejector-tube employed in the modification shown in Fig.

7. Fig. 9 is a perspective View of the point or Writing end of the outer shell, illustrating a modification in the construction.

A represents the sections of pencil or crayon, which may be of any suitable material and will preferably be sharpened or pointed at one end, as shown. The series of crayon or pencil sections will be inclosed in a tube B, the latter cut away or weakened, leaving sections or membranes ct at intervals corresponding to the joints between the sections of crayons, so that the sections of the tube B can be readily broken off when required. The solid portions of the tube B inclose about one-half of each crayon or pencil section and serve to assist in supporting the pencil-sections from lateral strains when in use, while the connecting membranes ct' are of a length equal to the remaining half of the crayon or pencil, so that the pointed or Writing portions of the pencil-sections come opposite the open spaces in the tube, as shown. At the point where the membranes a are intended to break they will be weakened, as at a2, so as to be sure to break only at those points.

The tube B, with its charge of crayon or pencil sections, will be inclosed in a casing or shell D, out through whose lower pointedV end D2 the sections of crayon or pencil will be ejected, as hereinafter shown. Surroundl ing the tube B is an ejector-tube either the Whole length of the shell D and projecting from the upper end, as shown in Fig. 1, in which E represents this tube, or in a short section E2, as shown in Fig. 7. In both forms the lower end of the tube E or E2 will be formed with converging spring-lingers l), adapted to engage the tube B and eject it, together with its contents, outward as fast as required. The lower end D2 of the shell D/ is contracted so as to pinch the first section of the tube B with suiiicient force to prevent the crayon or pencil sections from falling out by gravity, and the ferrule which forms the point of the shell may be formed with slits e, as shown in Fig. 9, which by their compression may be utilized to increase the grip .upon the pen cil or crayon sections.

In Fig. 1 the tube E is shown slidable outside the crayon or pencil tube B and held normally inward by a spring g. The tube E is formed open at the upper end and closed by a plug F, which may be of erasive material, such as rubber, so as to be utilized as an eraser.

In the modification shown in Fig. 7 the ejector-tube E2 is shorter and is slidable about the crayon or pencil tube B for a short distance by a stud h', passing outward through a slot h2 in the shell D.

In both forms the fingers b engage with the tube B at the breakable cavities, so that as the tube E or E2 is moved toward the end D2 the tube B will be carried alongwith it a distance equal to the length of one of the pencil or crayon sections, and thus provide a fresh writing-point as often as required. As each new section of the tube B is thrust outward it is broken oft at the point a2 and the short section containing the section of crayon thrown away,.leaving a portion of the next crayon protruding.

A number of the tubes B will be charged with IOO the series of the pencil or crayon sections A7 and provided in that shape for the user of the pencil, who has only to insert one of these charged tubes into the shell D' to renew the pencil as fast as it is worn out. Thus with one shell or casing D and a number of the much more convenient than the same numy ber of separate pencils.

The pencil or crayon sections being placed in the tubes D and sold in that shape'are much more convenient than if the .individual crayons were required to be inserted one at a time. zo .As before stated, thev separate pencil or crayon sections A will preferably be pointed, as shown, so that as each section is worn drown thenew section ejected will have a point `already thereon. The construction and operation of the tube B whereby the pencil-sections 'are supported from lateral movement are important features 'of my invention, as the severe lateral strains to which the points are subjected 3o arel thereby resisted, and the tendency to vibrate under the pressure of writing is coun- .A gtcra'cted. The pencil-sections being neces-I.

sarly short require a rigid support against efficiently supplied by the solid portions of thev movement, substantially as and for the pur'- pose set forth.
